We have a RedHat 7.2 box running squid-2.4.STABLE1-6. Today we started
getting these errors in /var/log/messages:
(squid): Too few authenticator processes are running
squid[26701]: Squid Parent: child process 5208 exited with status 1
dansguardian: Error connecting to proxy
In the cache.log, we get squid restarting about once a minute:
